Chemical composition of the essential oil of Centaurea grinensis Reuter and Centaurea apiculata Ledeb: Growing wild in Croatia and Bulgaria, respecti…
2016
AbstractIn the present study, the chemical composition of the essential oils from aerial parts of Centaurea grinensis Reuter (K) collected at Žuta Lova, near Senj (Croatia), and aerial parts (L1) and flowers (L2) of C. apiculata Ledeb. collected near Rebro village, near Breznik town, Znepole Region (Bulgaria), both belonging to subgenus Lopholoma (Cass.) Dobrocz, was evaluated by GC and GC-MS. The main components of K were 4-vinyl guaiacol (21.5%), hexadecanoic acid (16.2%), acetophenone (12.5%). Caryophyllene oxide (15.8%) together with sphathulenol (14.5%) and humulene epoxide II (9.4%) were recognized as the main constituent of both the aerial part (L1) and flowers (L2) of C. apiculata. …
Vaya valla! The phenomenon of "yeísmo" in oral Spanish in Valencia
2016
En los últimos años, el fenómeno del yeísmo ha sido abordado desde diferentes perspectivas; una de ellas es la sociolingüística, a la que nuestro trabajo pretende contribuir. El objetivo de este artículo es presentar cómo evoluciona el proceso fonético de deslateralización del fonema /ʎ/ a favor de /ʝ/ en el castellano de la comunidad de habla bilingüe de Valencia y su área metropolitana. Tradicionalmente se ha señalado que Valencia mantenía la diferenciación entre la lateral y fricativa palatales, pero estudios recientes dan cuenta de la introducción y expansión del yeísmo en determinadas comarcas bilingües de la Comunidad Valenciana. En el análisis sociolingüístico realizado actúan grupos…
Effects of oxygen fraction in inspired air on cardiorespiratory responses and exercise performance

Effects of overnight military training and acute battle stress on the cognitive performance of soldiers in simulated urban combat
2022
Understanding the effect of stress, fatigue, and sleep deprivation on the ability to maintain an alert and attentive state in an ecologically valid setting is of importance as lapsing attention can, in many safety-critical professions, have devastating consequences. Here we studied the effect of close-quarters battle (CQ battle) exercise combined with overnight military training with sleep deprivation on cognitive performance, namely sustained attention and response inhibition. In addition, the effect of the CQ battle and overnight training on cardiac activity [heart rate and root mean square of the successive differences (RMSSD)] during the cognitive testing and the relationship between ca…
Cardiorespiratory, neuromuscular and cardiac autonomic adaptations to combined endurance and strength training in ageing men and women

La ecología del mirlo Turdus merula en los naranjales: un estudio a largo plazo
2015
Se estudiaron algunos aspectos demográficos y de la biología reproductiva del mirlo común Turdus merula en una superficie de 17 ha dedicada al cultivo del naranjo en la localidad valenciana de Sagunto. Mediante la aplicación mixta de la técnica de la parcela y de la búsqueda de nidos se calculó el número de parejas nidificantes desde 1975 hasta 2015 y se obtuvo información sobre el tamaño de la puesta, el éxito reproductor y las causas del fracaso de los nidos. El programa de anillamiento llevado a cabo en cuatro sesiones anuales desde el año 2000 hasta 2009 proporcionó información sobre la filopatria natal, la proporción de sexos y la supervivencia de los adultos. La variación estacional d…
Post-exercise heart rate variability : a new approach to evaluation of exercise-induced physiological training load
2015
To improve maximal endurance performance, an optimal physiological training load, i.e. the balance between exercise and recovery, is required. In general, the goal of a single endurance exercise session is to transiently disturb body homeostasis after which a so-called supercompensation, an improvement in performance, can occur if the recovery period is adequate. The physical training load of a single exercise session consists of the combination of exercise intensity and duration. At the present time, there is no single tool to quantify the amount of disturbance of homeostasis that is equal to physiological training load of a single exercise session. Heart rate variability (HRV), the change…
Predicting and monitoring individual endurance training adaptation and individualizing training prescription : with endurance performance, cardiac au…
2016
Humans adapt differently to standardized endurance training programs. While some individuals may achieve huge improvements in physical fitness, other individuals may even suffer from negative adaptations. Special attention should be paid to identification of non-responders, which would enable to modify training to be more effective. Therefore, the aim of the present study was to investigate whether running performance, cardiac autonomic regulation and neuromuscular performance can be used in 1) predicting subsequent endurance training adaptations; 2) monitoring training adaptations; and 3) individualizing training prescription in recreational endurance runners. Three longitudinal training s…
Assessing game experience: Heart rate variability, in-game behavior and self-report measures
2014
Assessing game experience by means of recordings of physiological reactions elicited during game play is a technique that has gained popularity in recent years in the field of digital games research. However, since physiological signals are typically linked to several psychological processes, the use of some measures such as cardiac activity or heart rate (HR) remains problematic. The goal of the present study is to investigate to what extent game logs and self-report measures of game experience have a predictive value for heart rate variability during game play. Our results showed that the accurate registration of in-game behaviors by means of game logs carries the potential of providing r…
Cytotaxonomical investigation on Allium paniculatum ssp. exaltatum (Alliaceae) from Cyprus.
2004
Arare Allium endemic to Cyprus island, known as A. paniculatum subsp. exaltatum, is here examined. Relevant features in its morphology, caryology and leaf anatomy emphasize the marked taxonomic isolation of this taxon and allow it to be treated as a distinct species, proposed as Allium exaltatum. It is an exaploid plant (2n=48), probably arisen out of allopolyploidy and morphologically related only to some Middle East taxa.
